TAB O'R FINGER PIECE.

Application Afiled 7May 15, 1924. Serial No. 7l-3,504.

Vhave invented certain new and usefull Impr-evements in Tabs .or Finger Pieces.

The present invention consists of an improved tab or finger piece for attachment to a bound bookof leaves. A rigid plate, preferably of sheet metal, is formed of oblong Ashape `with a llongiitudinal `slot through which some of the leaves of the book may be threaded and having one or more shoulders projecting into the slot and adapted to engage the binding of the book of leaves for positioning the tab or finger piece at the binding edge thereof.

The improved tab or finger piece is particularly useful as an attachment for a small book of leaves mounted in a protecting pocket, in which case the tab or finger piece will project beyond the binding edge of the boo-k and the open edge of the pocket to afford a convenient linger hold for removing the hook from its pocket.

One use of the improved tab or finger piece is as an attachment to the ordinary book of stamps issued by the Government, the tab being easily applied to the book and changed from an old book to a new book when desired.

In order that the invention may be fully understood it will first be described with reference to the accompanying drawings and afterwards pointed out more particularly in the annexed claims.

Figure l is a perspective view of a bookenclosing pocket with the improved tab projecting therefrom;

Figure 2 is a similar view showing the bound book of leaves with the tab applied thereto;

Figure 3 is a detail sectional view taken through the central plane of the book and showing the improved tab or finger piece in elevation;

Figure 4 is a longitudinal sectional view taken on the line 4 4 of Figure 3;

Figure 5 is a detail perspective view of the tab or finger piece removed from the book;

Figure 6 is a view similar to Figure 3 showing a slight modification; and

Figure 7 iis sa face view of a tab or linger 55 ,piece embodying' :the features the tabs shown in both Figures 3 and 5.

l represents a book of vleaves bound in any suitable manner `such as by means of :the wire staples 2. 3 is an opened pocket 60 lof leather, or .other suitable material, adapted to contain the book of leaves l. 5 is the improved tab or vfinger .piece formed pref- .erab'ly of a sheet-metal stamping with a longitudinal slot 6 into which project .the 65 rend shoulders 7. lThe outer edge of the tab or finger piece is suitably shaped and ornamented to constitute a convenient iin ger hold.

In mounting the tab or finger piece upon a book of leaves, the leaves are separated approximately in the middle of the book and threaded or passed through the slot 6, and the linger piece passed up over the bound edge of the book of leaves as shown in Figures 1 and 3. In this position the shoulders 7 will be presented adjacent to or in engagement with the outside arms of binding staples Q as shown particularly in Figure 3, so as to prevent-lateral displacement of the linger piece upon the book.

In Figure 6 the finger piece 5 is formed with a central inwardly projecting lug Ior shoulder 8, which when the finger piece is mounted upon the bound edge of the book of leaves will be presented between the adj acent inner legs of the staples 2 and by its engagement therewith prevent the displacement of the finger piece upon the book of leaves.

In Figure 7 the finger piece 5 is shown with both forms of inwardly presented lugs or shoulders 7, 8.

"We cla-im:

l. The combination with a book of leaves bound adjacent one edge, of a slotted rigid plate inserted between said leaves and embracing the binding thereof and projecting beyond said bound edge to constitute a tab or finger piece.

2. The combination with a book of leaves bound adjacent one edge, of a slotted sheetmetal plate inserted between and embracing the bound edge of said leaves and projects ing beyond said bound edge to constitute a tab or finger piece.

3. The combination with a book of leaves bound adjacent one edge, and a pocket enclosing said leaves, of a slotted sheet-metal plate inserted between said leaves and einbracing the binding thereof and projecting beyond said bound edge and pocket to constitute a tab or finger piece.

4;. The combination With a book of leaves bound adjacent one edge, of a sheet-metal plate formed With a slot deined by a shouldered Wall, some of said leaves being threaded through the slot oi' said plate to present the plate between the leaves at the binding edge and a shoulder in engagement With the binding, and the edge of said plate projecting beyond said bound edge in the torni of a tab or linger piece.

5. An attachment for a bound book of leaves consisting'of a iiat sheet-metal plate formed with a slot to receive leaves and a shoulder projecting into the slot to engage the binding. j

6. A tab or linger piece fora bound book of leaves consisting of a slotted sheet-metal plate adapted to be inserted between the leaves to embrace the binding thereof and shoulder projecting into the slot in position to engage the binding to prevent displacenient of the tab or finger piece.

8. The combination with a book of leaves bound by wire-staples adjacent to one edge, of a tab or lingerpiece formed of a flat vsheet-metal plate slotted to be passed over the leaves into position to embrace the binding thereof7 and a lug or shoulder projecting into the slot in engagement with the Wire staple binding, said plate projecting beyond the bound edge of the leaves to constitute a tab or linger piece.
